PATENT JAMES J. HERVEY, OF RANDSBURG, CALIFORNIA.

CYANID-TANK.

srEcIFroATIoN forming part of Letters Patent No. 698,016, @lated Apri122, 1902.

Application nel November 2s, 1901. serial No. 83,405. (No motel.)

To all whom, it may concern,.-

Be it known that I, JAMEs J. HERVEY, a citizen of the United States, residing at Randsburg, in the county of Kern and State of California, have invented a new and useful Cyanid-Tank, of which the following is a specification.

This invention relates generally to tanks employed in treating ores with cyanid solutions, and more particularly to a tank whereby water and air or gas may be injected into the tank at the time the material is being l subjected to the action of the cyanid solution.

The object of the invention is to provide a tank whereby the operation of the solution is facilitated. I

The invention consists in the novel features of construction and combination hereinafter.

fully described, and pointed out in the claims.

In the drawings forming part of this specication, Figure l is a sectional elevation illustrating the practical application of my invention. the tank, taken on the line 2 2 of Fig. l; and Fig. 3 is a horizontal sectional view taken on the line 3 3 of Fig. l.

In carrying out my invention I employ a cylindrical tank A, which is preferably constructed of wood and is supported upon a suitable base or platform B.

C indicates a tapering circular ring or plate arranged at the bottom of the tank, said ring or plate resting upon the iiat circular plate D and which is bolted to the base or platform B, and connected also to this circular'plate Dis the central circular cone E, said circular cone E and tapering plate C constituting the bottom of the tank. Within the tank is arranged a metallic annular lining F, said annular' lining extending substantially parallel to the sides ofthe tank and also to the tapering plate C. This lining'does not extend entirely to the top of the tank A, but does extend some distance above the middle line of the same. The circular lining-space is divided into a series of vertical compartments by means of the vertical partitions G. An annular pipe I-I surrounds the tapering plate Cy and communicates with the tank at regular intervals, as shown at I, a valve being arranged at each point of connection, so that communication can be established or cut olf Fig. 2 is a horizontal sectional view of l between the circular pipe and any particular .compartment of the annular lining. A hotsaid pipe extendinginto the tank at its upper end,and,if desired,'this pipe may be connected to the Vertical branch pipe K', itbeing understood that the main pipe and all the branch pipes are provided with suitable valves, so that any particular portion can be cut off when necessary.

M indicates a vertical pipe extending upwardly from the main pipe K through the apex of the central cone E.

N indicates apipe extending into the bottomofthe tank into the V-shaped trough.

formed by the juncture of the central cone E and the tapering plate C, and O designatesa similar pipe leading from the bottom of the tank at the opposite side, said pipes N and O being intended to be used for charging and discharging the tank, said pipes being c onnected by means of pipes P, whichin turn are connected to a charging-pump Q.

R indicates a pump connected to the hotair pipe I-I for the purpose of forcing hot air intovthe annular pipe H.

.The lining F does not extend entirely to the bottom of the tank, as most clearlyshown in loo bring the cyanid solution into contact with the gold-bearing material, thereby producing the best possible results. i

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. A tank having an annular lining open at the bottom, said lining having air and Water pipes leading thereto, substantially as described. y

2. A cyanid-tank having an annular lining open at the bottom said lining being divided into a series of compartments, each com partment having an air and a Water tank communicating therewith, substantially as described.

3. A cyanid-tank having a tapering bottomt and the central cone arranged in connection with the said tapering bottom, the annular JAMES J. HERVEY.
